The decomposition of potassium nitrate (KNO₃) upon heating produces nitrogen gas (N₂), oxygen gas (O₂) and potassium nitrite (KNNO₃). Which of the following is the correct balanced chemical equation for this reaction?
सही उत्तर: ग) 2 KNO₃ → 2 KNO₂ + N₂ + O₂
This equation balances the number of atoms of each element on both sides. It’s a classic decomposition reaction demonstrating gas evolution. The other options are unbalanced and show incorrect products. This question tests balance chemical equations.

The mass percentage of carbon in C₆H₁₂O₆ (glucose) is calculated to be 40%. What is the mass of carbon in 100g of glucose?
सही उत्तर: क) 3.6g
The formula for calculating percentage composition is (mass of element / molar mass of compound) * 100. In this case, the mass of carbon is (40/180)*100=22.2%, which matches none of the options. The correct answer should be calculated based on the given percentages. This question tests understanding of percentage composition and calculation.

A solution has a pH value of 8. What is the concentration of hydrogen ions (H⁺) in this solution?
सही उत्तर: ख) 10⁻⁶ M
pH is defined as -log[H⁺]. Therefore, if pH = 8, then [H⁺] = 10⁻⁸ M. This concentration represents the acidic strength of the solution.

What is the primary purpose of adding an acid (like hydrochloric acid) to a soil sample during chemical analysis?
सही उत्तर: ख) To neutralize alkaline soils and adjust pH levels.
Acidification is often used in soil testing to determine the initial pH. Neutralizing alkaline soils with an acid (like HCl) brings the pH closer to neutrality, allowing accurate measurement of other parameters such as phosphate and potassium concentrations. Adding acid does not directly affect organic matter solubility or nutrient uptake.
